Embodiment Construction

[0029] figure 1 An embodiment of a fluid dynamic diagnostic and response system 100 is shown in FIG. System 100 preferably utilizes a fluid dynamic diagnostic system, such as figure 2 An embodiment of a fluid power diagnostic system 200 is shown. Preferably, systems 100 and 200 use predictive algorithm 201 to indicate when a fluid power system component (eg, one or more hoses) is approaching the end of its useful life. Various embodiments of systems 100 and 200 (such as figure 1 and 2 those shown in ) use modem 203 to transmit information about hose status, various vehicle / equipment specifications (e.g., machine type, machine identifier, and / or various machine fluid power system details and / or the ground location of the machine) to a central location (such as server 105 as shown). However, any wireless link (eg, conventional wireless telephones, Short Message Service networks and General Packet Radio Service (GPRS), Wi-Fi networks (including Wi-Fi mesh networks), etc.) m...

Abstract

Diagnostic and response systems and methods for a fluid power system acquire data from pressure and temperature sensors disposed in the fluid power system, analyze the data in a failure algorithm to build a history of cumulative damage to hoses in the fluid power system, communicates an indication of potential imminent hose failure to a central location when a level of the cumulative damage indicates imminent failure of a hose, analyze the information at the central location to determine an appropriate response, and transmit information about the fluid power system, including location, and identification of the hose about to fail to a response unit. The response unit responds to the location and replaces the component prior to failure, or the communication might include information that the hose has failed, such that the response unit replaces the failed hose to return the fluid power system to normal operation.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to earlier filed US Patent Application Serial Nos. 12 / 290,171 and 12 / 290,173 (filed October 28, 2008) bearing the same title, both of which are incorporated herein by reference. technical field [0003] The present invention relates generally to fluid power systems and components, and more particularly to monitoring and maintenance of such systems, and in particular to diagnostics and response for fluid power systems and components such as hoses systems and methods. Background technique [0004] The thrust of modern diagnostic systems is to use sensing technology and software to read and interpret real-world events and transmit data to alert the user if some form of intervention is required. Diagnostic systems are important to the performance and life of equipment in the automotive, marine and aerospace industries. Diagnostic systems that communicate fault warning messages are well kn...
